Patent GB-1333268-A (GB)
Title: Filtering
IPC: B01D39/06
Filed: 1971-01-19
Abstract: 1333268 Filtering liquids HYDROMATION FILTER CO 19 Jan 1971 2663/71 Heading B1D Liquid, particularly power station condensate is filtered to the order of 0.01 ppm solids content through a bed of alumina of above 99% purity and of average particle size 44-149 microns, the minimum thickness of the bed exceeding 1 inch. Prior to filtration, layers of the alumina are formed on pervious outlet tubes 15 in the manner of filter aid while vessel 10 is filled therewith to bury the tubes 15 and inlet tubes 16. These tubes are of similar construction, comprising stainless steel wire mesh or cloth supported by stainless steel pipes with perforations below 0.003 inches in diameter, but in Fig. 3 the lower ends of tubes 15 are connected to a drainage conduit. In Fig. 3, filtration flow is from valve V1 to valve V2 with other valves closed. When a differential pressure gauge or filtrate turbidity meter indicates that the bed is saturated, valves V1, V2 are closed and the bed is discharged into tank 41, agitated by stirrer 45 and allowed to settle, the liquid and separated dirt being decanted off through valve V5. Pump 55 then begins to draw clean water from tank 57 and delivers to the vessel 10 via an eductor 60, and valve V4 is opened to allow the cleaned alumina to be entrained therein. The valve V7 is opened to provide a closed circuit, and the alumina deposits first on the outlet tubes 15 as a filter aid, then fills the vessel as shown. Finally valve V7 is closed and V8 opened to wash from outlet tubes 15 into tank 57 any alumina which has penetrated tubes 15. Filtering flow is then restored. In the other embodiments, there is no bed circulation, the beds being cleaned by reverse flow of two or more times the filtration flow rate while keeping the bed compact by auxilliary flow. In Fig. 7, pump 112 delivers 90% of dirty liquid to inlet tubes 136 and 10% flows through T-pipe 118 and thence downwards to compact the bed. Inlet tubes 136 are modified by having internal tubes 164 extending almost to their floors. Cleaning is effected by opening valves V41 and V71 so that compressed gas from chamber 161 enters vessel 110 and forces the liquid therein out through inlet tubes 136 until the liquid level is down to the lower ends of tubes 164. This liquid may be residual from filtering, or the vessel could be drained and refilled before opening valve V71, and these steps could be repeated. 'In Fig. 4 (not shown) inlet tubes 136 have no internal tubes 164 and the bed is backwashed with filtrate from tank (114), a proportion of which is delivered through T-pipe 118 and the rest through outlet tubes 139. Valve (V11 or V42) may be repeatedly opened and closed to improve cleaning. In Fig. 9 (not shown) the multiple inlet tubes are replaced by a single central tube (171) which ensures a uniform bed thickness and eliminates dead volumes where solids might accumulate. When the fixed bed vessels are initially filled with alumina, liquid may be circulated to deposit the alumina on the outlet tubes.

Title: Apparatus and a method for detecting flaws on a surface of an  object
IPC: G01N21/55
Filed: 1972-02-24
Abstract: 1350189 Detecting flaws photo-electrically YA SKLYARSKY O M TESEOGLU and M P CHULOCK 24 Feb 1972 8563/72 Heading G1A In an apparatus for detecting flaws on a surface of an object 10 both the specularly reflected 12 and diffusely reflected 11 light resulting from illumination of the object by a light beam 9 are monitored. The source arrangement 1, containing an incandescent lamp 5, may be auto-collimating and contains also a polarizer 7, adjustable slit 13, and beam splitter 8. The "diffuse" path 11 contains an analyzer 14 so that the polarization state of the light may be investigated. For examining a rotating cylindrical radio component 10, the slit 13 is adjusted to give a rectangular incident beam. The outputs of the photo-multipliers 2, 3 are received by an analyzer 4, Fig. 2 (not shown). The analyzer input is amplified and separated into two components. The first component comprises a train of pulses, each pulse corresponding to a flaw. The second component is a random stream of pulses, corresponding to fluctuations in reflected light intensity. These two components are rectified and compared in a comparator (19) which measures the signal/ background ratio to produce a flaw signal when appropriate. This signal actuates a sorting device 18 which directs the tested objects into "accept" and "reject" hoppers.

Title: Fair cryptosystems and methods of use
IPC: G06Q20/00
Filed: 1993-04-20
Abstract: A method, using a public-key cryptosystem, for enabling a predetermined entity to monitor communications of users [suspected of unlawful activities while protecting the privacy of law-abiding users], wherein each user is assigned a pair of matching secret and public keys. According to the method, each user's secret key is broken into shares. Then, each user provides a plurality of "trustees" pieces of information. The pieces of information provided to each trustee enable that trustee to verify that such information includes a "share" of a secret key of some given public key. Each trustee can verify that the pieces of information provided include a share of the secret key without interaction with any other trustee or by sending messages to the user. Upon a predetermined request or condition, e.g., a court order authorizing the entity to monitor the communications of a user [suspected of unlawful activity], the trustees reveal to the entity the shares of the secret key of such user. This enables the entity to reconstruct the secret key and monitor the [suspect] user's communications.
